SHEET-METAL SHAFT-HANGER.

SPECIFICATION forming part of Letters Patent No. 767,271, dated August 9, 1904.

Application filed February 3, 1903. Serial No. 141,662. (No modelJ 1'0 (11M w/wm, it may concern.-

Be it known that I, HOWARD T. HALLownLL, a citizen of the United States, residing at Hallowell, in the county of Montgomery, State of Pennsylvania, have invented a new and useful Improvement in Sheet-Metal Shaft-Hangers, of which the following is a specification.

My invention consists of a novel construction of sheet-metal shaft-hanger which can be cheaply manufactured and is strong and durable.

Figure 1 represents a side elevation of the hanger. Fig. 2 represents an end elevation. Fig. 3 represents a section on line a? a, Fig. 1. Fig. 4 represents a section on line ;1 Fig. 1. Fig. 5 represents a section on line 2 2, Fig. 1. Figs. 6 and 7 represent a sectional view and a side elevation, respectively, of a modified construction of intermediate brace. Fig. 8 represents a front elevation of the hanger-leg seen in Figs. 1 and 2, on an en larged scale. Fig. 9 represents a side elevation of the hanger-leg seen in Fig. 8. Fig. 10 represents a section on line .2, Fig. 9. Fig. 11 represents an end view of the hanger-leg seen in Fig. 8. Fig. 12 represents a sectional view of a modified construction of hanger.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, each hanger-leg 1 has a longitudinally-extending hollow rib 2, which has the upper portion 4 deflected outwardly and the upper terminals 5 deflected so as to form feet whose outer ends are closed, as at 6, it being understood that the rib 2 extends throughout the entire length of the hanger.

7 designates members which extend laterally from the sides of the rib 2, said members 10 and 11 pass through these points to hold in position the ends 12 and 13 of the yoke 14, in which is rotatably mounted the adjusting device 16. Upon this device is supported the box 17, the upper portion of which box is held in position by the upper adjusting device 23. This device is held between the parts of intermediate brace 18, which consists of the pair of plates 19, having the strengtheningribs 20, said plates having flanges 21 which are secured to the members 7 by rivets 22. By removing a bolt, as 10, the yoke 14 can drop, as seen in Fig. 1, thus rendering the box 23 accessible and removable. The plates 19 are braced by the bolts 24. A plate 25, bridging the space between the feet 5, may be used, or, if desired, said plate may be omitted. It will be noted that this plate extends between the extemities of the closed ends .6 and is riveted thereto, as shown at 25 The depth of the flanges 8 is increased or decreased according to the drop of the hanger.

In the construction seen in Figs. 6 and 7 the intermediate brace 26 is composed of a plurality of plates having one or more curves and held in assembled position by fastening devices 27, the lower portion of said plates being enlarged, so as to contain the block 28, through which passes the adjusting device 29, which, it will be understood, can be used in place of the adjusting device 23. (Seen in Figs. 1 and 3.)

In the construction seen in Fig. 10 I have shown the central longitudinally-extending hollow rib 30 as provided with the rounded portions 31 instead of being constructed as seen in cross-section in Fig. 5.

In Fig. 12 I have shown the lower extremities 32 of the hanger-leg as being reinforced by plates 33, which may be employed, if desired.

It will be understood that we may in certain cases not close the flanges 8 upon the body portions at the lower end of the leg, as shown in Figs. 2 and 11, but let the flanges on the outer edges taper gradually as they approach the lower end of the legs; but owing to the increased strength of closing the end of l a pair of integral legs and feet each formed the leg as shown the construction shown is 3 ing flange at each side of said rib and flanges Special attention is called to the fact that I preferred.

make the legs with a widened base gradually terminating into narrow portions at their lower end,whereby the lower brace is strongly 1 a brace connecting said legs mtermedrate their and neatly coupled to the legs, giving the greatest possible strength lVhen the construction shown in Fig. 6 is used for the brace, I prefer to insert lateral adjusting devices in the legs to take the side thrust of the box.

Slight changes may be made by those skilled in the art, and I have not shown nor described all modifications which 1 consider coming within the bounds of this invention.

Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent. is-- 1. In a shaft-hanger, an integral leg and foot formed with a central hollow rib, a latorally-extending flange at each side of said rib and flanges extending angularly from the outer edge of said lateral flanges, said rib and said. flanges extending throughout substantially the length of the 2. In a shaft-hanger, an integral leg and foot formed with a central hollow rib, a laterally-extending flange at each side of said rib and flanges extending angularly from the outer edges of said lateral flanges, said rib and said flanges extending longitudinally from the extremity of said foot to the lower portion of said leg.

3. In a shaft-hanger, an integral leg and foot formed with a central hollow rib, a latorally-extending flange at each side of said rib and flanges extending angularly from the outer edges of said lateral flanges, said rib and said flanges extending longitudinallyfrom the extremity of said foot to the lower portion of said leg, the outer end of said rib being closed at the extremity of said foot.

4. In a shaft-hanger, an integral leg and foot formed with a central rib, a laterally-extending flange at each side of said rib and flanges extending angularly from the outer edges of said lateral flanges, the lower ends of said angularly-extending flanges reinforcing the lower end of the leg.

5. In a shaft-hanger, an integral leg and foot formed with a central hollow rib, a laterally-extemling flange at each side of said rib and flanges extending angularly from the outer edges of said lateral flanges and reinforcing the lower end of the leg, said reinforcing portion being pierced to adapt it to receive a support.

6. A sheet-metal shaft-hanger comprising with a central hollow rib, a laterally-extendextending angularly from the outer edges of said lateral flanges, said rib and said flanges extending longitudinally from the extremity of said foot to the lower portion of said leg,

length and rigidly secured to said lateral flanges, and a yoke connected to the lower ends of said legs.

7. A sheet-metal shaft-hanger comprising a pair of integral legs and feet each formed with a central hollow rib, a laterally-extending flange at each side of said rib and flanges extending angularly from the outer edges of said lateral flanges, the outer ends of said ribs being closed at the extremities of said feet, a brace connecting and rigidly secured to said legs intermediate their length,a yoke connected to the lower ends of said legs and a plate connecting said feet, the ends of said plate being secured within the outer ends of said ribs at the extremites of said feet.

8. A sheet-metal shaft-hanger comprising a pair of integral legs and feet each formed with a central hollow rib, a laterally-extending flange at each side of said rib and flanges extending angularly from the outer edges of said lateral flanges, the lower ends of said an gularly-extending flanges being shaped so as to reinforce the lower ends of said legs, a brace connecting said legs intermediate their length and a yoke secured to both sides of each of the reinforcing ends of said legs.

9. A sheet-metal shaft-hanger comprising a pair of legs with integral feet each formed with a central hollow rib, a laterally-extending flange at each side of said rib and flanges extending angularly from the outer edges of said' lateral flanges so as to reinforce the lower ends of said legs, the reinforcement being pierced to receive a belt, a bolt fitting therein, a brace connecting said legs intermediate their length, a yoke connecting said legs at their lower ends and inserted between said reinforced portions of each of said legs and bolts connecting said yoke with each of said legs.

10. A shaft-hanger comprising a pair of legs and a brace secured to said legs intermediate their length, said brace having a hollow strengthening-rib provided with flanges at angles with the rib, engaging the inner portions of the legs.
